SPLIT PULLEY,

Application led'lebruary 10, 1926, Serial No. 87,416, and in FrancelMarch 1G, 1925.

outer band is' fastened to the pulley body through its middle or centralportion, whilst projections, integral with or rigidly connected to thepulley body prevent the axial slipping of the outer band, thelatterbeing provided for this purpose with suitably situated and elongatedopenings.

In the accompanying drawing, showing by way oi example one lembodimentof the invention: i

Fig. 1V is a side elevation with parts broken away of a pulleyconstructed according to the invention.

Fig. 2 is a view of the pulley, illustrated lia-lt in diametricalsection and half in plan.

8 is a partial enlarged view of a guiding stud. y y

The pulley body is divided into two symmetrical parts 1 1, said pulleybody being secured onto the shaft (not shown) by means of bolts 2extending through the hub. The outer band 3, which receives the belt, iscomposed ot two similar partsA or sections.

Finch part or section 3 of the outer band is permanently mounted on eachhalf l of lthe pulley body, the connection between the cured to thepulley body l-l and extending I slightly radially outwards so as toengage in elongated slots 8 suitably formed in they outer band 3.

Alternatively the studs can be made separately and screwed into the rimas shown in Fig. 3.

It is to be understood that the details of `construction'ot the pulleyabove .described be modifie-d in various ways without departing from theinvention. In particular, the pulley body as well as the outer band,canv be divided into more than two sections. I claim: f l. A splitpulley comprising a liubmembei', a rim member, connection means betweensaid hub and rim members, a sectional outer band, av single connectingmeans securing each section of the band to the rim inember of the pulleybody vthrough its central portion and adapted to prevent slipping of thebandl in circular direction, the partsot the band on either side of saidcentral connection being provided with elongated slots, and means onvtherim member entering said slots and adapted to prevent the slipping lof the band in axial direction.

2. A split pulley comprising a hub member, a rim member, connectionmeans between said hub and rim members and a sectional outer band, asingleconnecting means securing each section of the band to the rimmember of the pulley body, through its cen-v tral portion and preventingslipping in circular direction and a series vof connecting memberspreventing axial slipping but allowing iree slipping in circulardirection.

3.In a split pulley according to claim 2, a permanent connection betweenthe rim member and the central portion of each oi' the parts of theband, and spaced projections on the rim part entering elongated slotsformed in said parts of the band.

4. In a split pulley according to claim 2, a permanent connectionbetween the rim member and the central portion of each of the parts ofthe band, elongated slots formed in the said parts on either side ofsaid connection, and means entering said slots and inserted in the rimpart of the pulley body.

LOUIS ROUANET.
